Abstract

(NBun4)3[Mo6O18(N2C6H5)] has been obtained by treating (NBun4)2[Mo6O19] with an equivalent amount of phenylhdyrazine in benzene. X-ray crsytallography reveals the identity of the deep red crystalline material as a polymolybdate species incorporating a coordinatively bound organo-diazenido unit. The anion [Mo6O18(N2C6H5)]3- is structurally similar to the precursor [Mo6O19]2-, with the terminally bound phenyldiazenido group replacing a terminal oxo unit of the hexamolybdate moiety. (NBun4)3[Mo6O18(N2C6H5)] crystallizes in the orthorhombic space group Pmcn with a = 17.162(3) Å, b = 17.577(3) Å, c = 23.860(4) Å, V = 7197.7(8) Å3, Z = 4, and Dc = 1.56 g cm-3 [μ = 10.60 cm-1, Mo-Kα (λ = 0.71069 Å)]. Solution and refinement based on 2118 reflections with Io ≥ 3σ(Io gave a final reisdual of 0.080.
